Heteronuclear Diatomics Flashcards
1
Q
When orbitals of different energies combine, what is the effect on the energies of the resultant MOs?
A
The bonding MO is not lowered in energy as much, and the anti-bonding MO is not raised as much.
2
Q
How can MOs be asymmetrical?
A
Due to one atom’s AOs being closer in energy to the anti-bonding MO and the other’s AOs being closer in energy to the bonding MO, they contribute more to one MO than the other.
3
Q
True or false? The unequal sharing of electron density increases the ionic character of a bond.
A
True.
4
Q
What is the equation for bond order?
A
1/2(Number of bonding electrons - number of anti-bonding electrons)
